An object's rectangular elements are the position and velocity components relative to the object's parent.

The

**Orbital Position**is the vector that describes the position relative to the object's parent.The

**Orbital Velocity**is the vector that describes the velocity relative to the object's parent.

The rectangular elements are as follows.

**Orbital Position X**is the x-coordinate of the orbital position, and has the symbol**rx**.The x-coordinate of the orbital position may be any number.

**Orbital Position Y**is the y-coordinate of the orbital position, and has the symbol**ry**.The y-coordinate of the orbital position may be any number.

**Orbital Position Z**is the z-coordinate of the orbital position, and has the symbol**rz**.The z-coordinate of the orbital position may be any number.

**Orbital Velocity X**is the x-coordinate of the orbital velocity, and has the symbol**vx**.The x-coordinate of the orbital velocity may be any number.

**Orbital Velocity Y**is the y-coordinate of the orbital velocity, and has the symbol**vy**.The y-coordinate of the orbital velocity may be any number.

**Orbital Velocity Z**is the z-coordinate of the orbital velocity, and has the symbol**vz**.The z-coordinate of the orbital velocity may be any number.
